NAJHQ - Hazzat’s Query

no tags 

Hazzat is a new guy in computer science. Now he read in 4th semester. Recently he completed the course data structure. After finished data structure course he can realize that those are not enough for his. Every day he fall in a new (data structure) problem and want solve it, but those problem he can’t solve using his know data structure. He want to establish new data structure. But he always failed to establish it. Now help Hazzat to establish a new data structure following problems.

Today Hazzat problem is:

Given a N size array (arr[N]) initialize all the element value to exactly c.

Pseudocode:

for(i=1; i<=N; i++)
    arr[i] = c;

Today Hazzat want to do 6 types of task.

i) add k to array index u to v

Pseudocode:

for(i=u; i<=v; i++)
    arr[i] = arr[i] + k;

ii) subtract k from array index u to v

Pseudocode:

for(i=u; i <= v; i++)
    arr[i] = arr[i] - k;

iii) add k to array index u

Pseudocode:

arr[u] = arr[u] + k;

iv) subtract k from array index u

Pseudocode:

arr[u] = arr[u] - k;

v) reset a array index u with k value

Pseudocode:

arr[u] = k;

vi) find the current value of array index u

Pseudocode:

print arr[u];

Here the array is 1 base index.

Input

Input start with an integer number T (≤ 10), which is number of test cases.

For each test case, first line contains N Q c where N is array size, Q number of queries and c is the initial value of array elements.

Next Q line give Hazzat's tasks

add u v k (add k to array index u to v)

minus u v k (subtract k from array index u to v)

addin u k (add k to array index u)

minusin u k (subtract k from array index u)

reset u k (reset array index u to k)

find u (print current value of array index u)

Constraints

  • T ≤ 10
  • 1 ≤ N, Q ≤ 10^5
  • 1 ≤ u ≤ v ≤ N
  • 0 ≤ c, k ≤ 10^9

Output

For each case, print “Case #X” where X is the case number.

After next line print value of array index u where Hazzat want to know. (only for find u task)

Output a blank line between two cases.

Sample

Input:
2
10 3 3
find 4
add 3 7 3
find 5
10 10 3
find 4
add 3 7 2
find 6
minus 3 4 1
find 4
addin 4 5
find 4
minusin 4 2
find 4
find 10

Output:
Case #1
3
6

Case #2
3
5
4
9
7
3

Note

Output number may be negative.

Data set is so huge, use faster I/O

Normal lazytag but AC by colse stream synchronization (~ ̄▽ ̄)~

Lazy needed some constant opti (i.e. minimize # of operations with long long num). These kinds of problems would be a little nicer with +10% TL.

lazy straight forward

Nice ques!

@Varun try solving using BIT

vb30: 2014-11-21 12:47:38

Lazy Prop giving TLE ...

@Md. Najmuzzaman thank you for this problem :)

You are welcome @Archangel.
